Logline

Mifuyu, the daughter of the prestigious Rattigan family, has lost her entire family except her brother and been forced into exile as part of some massive conspiracy. With her dead father's secret weapon, a mechanical beast called Yajusha, Mifuyu attacks and destroys her enemies in order to clear the false accusation and restore the Rattigan family’s reputation.

Planning Intention

The story is set in a world of the unique collaboration of medieval European fantasy and the SF element of mechanical beasts. It is a human drama in which the siblings who have lost their home and family and have been forced into exile as part of some massive conspiracy fight against their harsh fate, sometimes at the expense of their loved ones.
If I develop this unique worldview into a visual work, I believe it can attract many people.
Also, it can be developed as a simulation game with mechanical beasts like Azur Lane or a role-playing game with characters like in Yin Yang Teacher.

Synopsis

Set in the medieval Claudia Continent where many chivalrous nations are preoccupied with territorial disputes.

The Fabius Empire, one of the chivalrous nations, holds the chivalric order Quint, known to be the world's strongest.

The protagonistMifuyu and her younger brother Kent live with their father Kariam Rattigan, the commander of the chivalric order Quint.

Due to the conspiracy concocted by the Winthrop family, who is responsible for the darker aspects of the government, such as spying and assassinations, Kariam and the rest of the Rattigan family were decapitated. Mifuyu and Kent, who are the legitimate children of the Rattigan family, are targeted without exception, but luckily escape the predicament thanks to the aid of Mifuyu’s fiancé Graham.

However, Wiesel Winthrop is aware of their escape. Wiesel, who has become the eternal commander of the chivalry order, issues an order for their capture and releases hunters to find them.

To escape from the capital, Mifuyu and Kent run into a derelict castle in the forest.

In the basement, there is a mechanical beast Yajusha which their father had received from the emperor.

The Quint have considered the mechanical beast as an inferior weapon in the past and abandoned it in respect to tradition and formalism. Mifuyu and Kent get on the mechanical beast and leaves for a safer neighboring country, but a hunter blocks their way.

The hunter is Mifuyu’s fiancé Graham, who helped them to escape. Wiesel Winthrop has taken Graham’s family hostage and forced Graham to hunt and eliminate Mifuyu and Kent. Graham’s serious situation does not allow for him to be merciful, so Mifuyu makes up her mind to fight against him.

In order to protect the legacy of the Rattigan family, Mifuyu decides to relinquish her identity as a human and a woman, and slashes down the man who once she loved with the sword of the beast. "Because of personal reasons, my body is already dead and I have become a beast. I will sacrifice myself for my brother, the son of heaven, to rule the military government.”

Mifuyu and Kent have become fugitives after being charged with the imperial assassination. In order to survive and to revive the Rattigan family, there is no choice but to make Kent a new emperor of the Fabius Empire. Mifuyu commits to her cause and continues to operate the mechanical beast. Struggling to earn the necessary money for the revive the family’s position, Mifuyu undertakes assassination jobs in various parts of the continent while fiercely fighting against thugs and beasts of the Winthrop family who tries to eliminate Mifuyu and Kent.

Even though she was the firstborn, her role was to escort the male heir, so she was forced to learn swordsmanship and martial from early childhood. There were occasions when she taught swordsmanship to the sons of other knights.
On the day before her wedding with Graham, due to Winthrop family’s plot, her father was charged with the assassination of the son of Emperor Fabius and the family fell apart.

To survive, she must earn money, start a revolution to overwhelm the imperial family, and make Kent the emperor. In order to make Kent the emperor of the Fabius Empire, she gives up her happiness as a woman and pledges to do whatever it takes.

●Kent Rattigan 13 years old
He is the son of Kariam Rattigan, head of the Rattigan family and the former eternal commander of the chivalry order of the Fabius Empire. Since he was born, he has been educated to inherit his father’s position. He has been learning swordsmanship as well, but is not very skilled because of his innocent personality. He is still young and wants to play. He is unable to accept the reality of suddenly losing his parents. Although he often tries to escape from reality, he watches his sister fight as they travel, and he gradually starts to accept his destiny to rule the empire.

●Wiesel Winthrop 50 years old
Former secret chief of the chivalry order of the Fabius Empire. He’s taken over Kariam’s position and become the eternal commander of Quint. He also serves as the chief magistrate. He’s been engaging in assassinations. He framed Rattigan family for the purpose of fulfilling his family's wish. He seems to be a gentle character at first sight, but he doesn’t feel any pain in using others. Because of his former position, he is one of a few people in Quint who can operate the mechanical beast. While noticing the effectiveness of the mechanical beast, he pretends to be disrespectful of the existence of it with some political reasons. He’s planning to assassinate Fabius and to make his own son be the emperor.

●Elbert Winthrop 28 years old Male
The second child of the Winthrop family. As the eldest son died, he’s the heir of the family and also serves as a consular officer assisting his father. Unlike his elder brother who was a reliable successor, Elbert’s inconsiderate personality and lack of a sense of morality are always a concern of his father, Wiesel. However, his swordsmanship is first-class, and he is also an excellent operator of the mechanical beast.

●Heine, The Reaper 20 years old Female
The secret messenger of Guys Guild. She is a beautiful female Reaper who can operate the mechanical beast and watches over Mifuyu and Kent traveling the continent. She assigns assassinations. Initially, she was cold-hearted and unfriendly, but gradually she began to care about Rattigan's siblings, especially Mifuyu. Guys Guild is an approved free trade city, where there are weapons merchants operating. The union of weapons merchants gives Mifuyu the opportunity to make use of Yajusha as much as possible. Their purpose is to make people realize the effectiveness of the mechanical beast during battles.
●Mechanical Beasts
Mechanical beast is a robot which is about 20 meters in length. The original robot was cast ashore on the coast of Claudia Continent and found several decades ago. Yajusha is a prototype and since being created, copies of it have been produced in many countries. However, in current battles, the chivalry is regarded highly and they believe using mechanical beasts for battles is considered despicable.
Therefore, it is prohibited to produce and use mechanical beasts individually in countries.
In reality, fugitives and villains use them to escape from the hunters.
The Guys Guild noticed the effectiveness of the mechanical beast in early stage and has been planning mass production and illicit sales.
Yajusha has been hidden in the derelict castle in the Fabius Empire because of its outstanding fighting ability.
